.As shown in. Fi

end of 'the vertioa posts secured a small arm with a Collar.

which may be a screw s01 as-to the steer-111g lever m of the-motorc'ar.

mentof the steering lever'm is transmitted through the rod k tothe ar n 2'; thereby-tnrnmg n one direc-tionor the other the lamp.

post 'to" which the" arm/i is secured. turning movementof the lam i post b is transmitted through its arm h, the rod q connected therewith, thejarm f 'to whieh this". rodisoonnected and to the transverse shaft d, which isfthereby rockedinone'direction or the other. This rocking 'movement of I shaft cl is transmitted to the this arm fto its rod 9 and arm' I and from therefrom three other lamp post so that both the lamps hits short armh :tothe' are simultaneously turned in'corresponding the transverse arln (Z, while the other endoii directions.

'In order thatpthe light a projected by the lamps be directed in the same direction as the vehicle is running, the position of the collar l is'adjusted so that the ang ila r displacement of the lamps correspondt exactly to the angular displacement of the wheels of the vehicle.

The desired result is thus obtained by means of a device of a very simple construction, easy to be adopted on every motor car and which works without interfering in any manner with the op ration of the motor car, as the etlort necessai y to turn the lamps is practically so slight that'no additional resistance at all is felt on the steering wheel, which is an essential condition to not interfere with the safety of traveling with the vehicle.

In some instances, it may be desirable to place the connecting rod above the frame member of the car instead of beneath the same. "his inay be done as illustrated in Flg. 4:, by extending the steering; lever m in an-arm indicated at n and connecting the arm "n by a suitable link 71: with one of thearms f secured to the transverse shaft (Z; or as shown inllig. 3, I may employ a lever osuitably connected to the frame of the car, and connect one end of the lever 0 by a rod with one of the arms f secured on the lever 0 connected to the steering lever m by the same collar l as hereinbefore described and the rod 70 1 In order that the construction of the parts connecting the rotatable lamp postswith the steering le'vero'f the car may be readily 'understood, reference is made to Figs. .5,to 10 inclusive. By reference to Fig. 5, the construction of these parts as employed in the form of the invention as shown in'Fig.

1, is illustrated. The arm 72 is securely connected to one of the lamp posts I) in any de sired manner. The free end of the arm 7i terminates in a reduced portion 20: The

rod g at one end is provided with a head 21,

terminating in lugs 22. Fitting over and jonrnaledon the reduced portion 20 of the arm 72. is a head 28. and on the head 23 there is a' lug 24 adapted to pass within and fit the recess between the lugs 22 on the head- 21.

Through suitable holes in the said lugs 22 and 24, a pin is passed to pivotally connect the same.

On the opposite end of the ma o, ahead 26 is secured. This headpsimilarly to the head 21, is provided with spaced lugs 27,

and the head 21 and the head 28 are so se- I cured to the. rod'g that; when the ln the head 21 are in a horizontal position which they assume when in use. the lugs 97 on the head 26 are in rertical position.

Journaled on the free end of the arm f is a collar 28, onwhich collar is a lug 29 adapted to pass within the recess formed by the lugs 27 in the head 26, and the lugs 27 and 29 are secured togetl ier by a pin 30 which passes. through holes provided in these lugs for this purpose, and the collar 28 is cured in position on the end oil the 'arm 1" bya cotter-pin 3]. or otherwise. 3

Now referring to lf lfgS. (3, 7 and 8. it will be apparent that the construction oi the joints between the collar 28 and the rotatable lamp posts in the same is the same as that hereinbe'tore described in connection 'with Fi 5. ln this constructimi shown in Figs. (3, 7 and which is that employed in the modified 'forms'of the invention shown in Figs. 3 and 4-. the partcorresponding to'the collar :38 is n'c'tcraliilymade in halves, as clearly indicated in Fig. 8. One of these halves -32 is connected to the head 26 in exactly the same manner as is the collar 28, as shown in Fig. and the other member is similarly iournalcd on the end of the arm f and is connectml to the end of the rod k. as shown in Fig. 4, or the rod h shown in Fig. 3.

Referring to Figs. 9 and 10. the collar Z is preferably made in two parts. 34- and 37 provided with a recess 36 to receive the steering lever m. and secured together by the bolts 37 or otherwise. The members 34, 35, of this collar are provided with spaced apart arms 38 adapted to receive the screws 40.

On the adjacent end of the lever Z there a head 4-2 and this head is provided with arms-4?). similar mall respects to the arms 38 and each provided with a screw it similar to the screws 40.

4-5 designates a ball in a line on whose circumference in equally spaced positions.

recesses. are provided torcccive the ends of the screws 40. tl lndfiy which con triu-lion. manifestly. a universal joint is madc hctween the 'collar Z and the rod Z".

I claim as my invention:

1. A. device for turning the headlights of motor cars. comprising rotatable posts for the-lamps. bearings for the samc'fixcd on the frame members of the vehicle. a transverse shaft mounted in bearings fixed on the frame members of the vehicle. two armscarricd by the transverse shaft. rod universal joints between the corrcsrmndinn ends of. the said rods and the said arms. universal joints connecting the olhcr ends of the said rods and the said posts. and a connccting rod for operating lhc rotatable post's. one cnd of which is connectcd with the steering lover of the rchicle. I

"2. A device for steering: the head-lights of motor cars comprising tworotatablc' posts for the lamps. a transverse shaft. arms scoured on said transversesha'l't, rods, universal joints con cting the corresponding ends of the said rods with the said arms, universal joints tween the other ends of the said rods and the said posts, and a rod for operating the aforesaid'meinbers fromthe steering lever or" the vehicle.

rods with the ar ns secured to the said r0- tatahle posts, an armsecured to the lower end of one of said rotatable posts, and means connecting the last aforesaid arm to the steering gear of the car to turn the head-lights as the steering Wheels are turned.

'5. An apparatus for turning the headlights of motor cars, comprising rotatable posts upon which the head light lamps aresecured, an arm connected to each rotatable post, a transverse shaft, lever arms .con nected to the transverse shaft, rods, universal'join ts connecting the corresponding ends of the said rods with the saidlever. arms secured to the transverse shaft, universal joints connecting the'other ends of the said rods wichlthe arm's secured to the said r0- posts, an-farm secured to the lower end or" one oi the said rotatable posts, a rod pivotally connected at one end to the last necting the opposite end of the last afore said rod to the steering lever of the'car.

In testimony whereof I have afiixediny signature in presence of twowitnesses.
